CLOSURE Filed April 2.v 1931 Patentedl Jan. y5, 1932 UNITED STATES yN'IBHFIRED M. BROOKS, OF WEST' ORANGE, NEW JERSEY cLosUnE Application ledfApriI 2, 1931.` Serial No. 527,139.

The present invention relates generally to closures, and has for its main object and feature the provision of means to alford a reliable and inexpensive sealing medium to be associated with al sheet-material cap employed in connectionk with an open-mouth container, such as a milk bottle. n

In the accompanying drawings the invention is disclosed in a. concrete and preferred form in which:

kFig. l is a view in elevation of a device embodying the invention;

F ig. 2 is a vertical sectional view substantially on theplane of line 2-2 of Fig. 1'; and

Fig..3 is a horizontal sectional view substantially on the'plane of line 3 3 of Figs. l or 2.-

Y l indicates an open-mouth container, herey a milk bottle, havinga neck-portion 2 provided with acircumferential ledge 3 above which are screw-threads'. 4 is a cap of sheet material having threads 5 to engage the threads of the neck of the bottle, and having also a closed top 6 and a circumferential bead 7 below the threads.r When this cap is screwed on thev neck of the bottle, bead 7 is located just above ledge 3 of the bottle. 8 is a sealing element of sheet material adapted to surround the neck of the bottle and is provided with a circumferential groove 9 to receive bead 7 Said element is further pro vided with an upper and a lower flange 10 and 1l. Flange l0 is adapted to extend over the top of the cap and flange 11 to engage beneath ledge 3. Suitable means such ask bolt l2 connectsrthe free ends 13 of the sealing element.

It will be seen that by the construction above described, it is possible to have flanges V bead 7. Not only does this lessen the amount` l0 and 11 of very narrow width Without sacrificing a proper grip on the bottle, because groove 9 is in intimate engagement with of metal required and therefore cuts down expense, but it also avoids the difficulty en- .enclose the cap and ledge, provided with an intermediate circumferential groove to receive the bead on the cap and having an upper and a lower flange, the former to eX- tend over the top of the cap and the latter to engage beneath the ledge.
